Selena Gomez might have teased her engagement manicure at the Chanel Academy Women's Luncheon on Dec. 11, but she saved the engagement ring itself for a dazzling Instagram debut hours later. The singer revealed she and producer Benny Blanco are engaged with a close-up shot of her new jewelry set on a pale pink backdrop. Not that she needed to zoom in, because the diamond is objectively huge.
As the Emilia Pérez star shared the news with family and friends, clad in her favorite Banana Republic jeans and a fur coat, onlookers quickly caught on to the ring's touching backstory. Gomez is wearing a marquise cut diamond, a style that Ann Grimmett, VP of Merchandising at Jared Jewelers, estimates makes up only 5 percent of all diamonds sold today. It's a shape that originated in eighteenth century France, when King Louis XV requested a diamond cut into the shape of his lover's lips, the Marquise de Pompadour. Its rarity has made marquise diamonds a top choice for celebrity engagement rings centuries later, from Jennifer Lopez and Ben Affleck's first go-round to David Beckham and Posh Spice. More importantly, the cut is just "Rare" enough to have gotten a shout-out in Gomez's 2015 song "Good for You."
